TO .ALL WHOM IT MAY OONCERN:

i Be it known that we, DAVID SAnvEn and Ronsnr Cooxs, both ofGreensburg, in the county of Westmoreland, andl State of Pennsylvania,have invented certain new and useful Improvements in Corn-Harvesters, ofwhich the following is a full, clear, and exact description, referencebeinghad tothe accompanying drawings,-Which v make part of thissp'eeiiicatiomand in whichv Figure l represents a plan or top view ofainaehine embracing our improvements, and

Figure 2 a view, in elevation, of` the same, as seen from the dividerside of the machine. The red lines in this figure show the attitudeassumed by the dumping-apparatus at the moment of-'discharging thegavel. I I I I It is the objcctof our invention to discharge the eutstalks fromthe'machinein gavels'suitable for binding, and in a positionout of the way of the team in cutting the nent swath; and to this endthe improvements herein claimed consistl I First, in a novel method ofconstructing a eutoif,-to receive the falling stalks while the completedgavel is bein'g discharged, said eut-off 'having a. movementsubstantially parallel to the path of the machine.

Second,l in a novel method of combining a vtiltin'glplatform with acut-off, vibrating endwise at a right angle I tothe axis of theplatform, and parallel to the path of the machine.

Third, in a novel method of eombiningn guide, to defiectthe eut stalks,a platform, to receive and discharge them, and a cut-off, tointercept'thc fall of the stalks cut during the discharge of thepreviously-accumulated gavcl. v v f Fourth, in a novel method ofcombiningT with a reel, revolving-on a vertical axis, or one nearly so,a tiltingplatform, which drops the stalks swept upon it by the reel. f f

` Fifth, in a. novel` method of combining, in a har vester,alaterally-projecting cutting-apparatus, to sever the stalks, a. rel, tosweep the cut stalks backward, a guide, to deflect the cut stalks, atilting-platform, to discharge them, and a cut-off, to be interposedduring the tilting of the platform. 'f i Sixth, in'a novel methodof/combining `a main frame, a supplementary, frame, hinged to saidmainframe, und an interposed adjusting-arm,carrying a supporting-wheel, I

In order to carry out the objects of our invention, wemount a stout mainframe on proper supporting and driving-wheels. In rear of this mainframe, welattuch` a platform, projecting laterally beyond `the mainframe, and carrying' a cutting-apparatus, of any'well-lcnownconstruction, actuated by proper gearing from the drivingwheels. Avertical shaft on the platform carries horizontal arms, which serveto`pr`ess the stalks against the cutting-apparatus, by which they aresevered. When cut, the continued rotation of the reel-arms-turns the istalks, which remain upright,`and, by the aid ofa curved guide,causesthem-to fall upon theplatform at right angles to the path of themachine, This platform is pivoted, so as to tiltion an axis transverseto the'path-of 'the machiue,vand to drop' the gevel upon the ground; Itis operated by a compound lever, 'worked by 'the driver. A guard orcut-offis so connected with the tilting-platform that, as the gavel isdischarged, the cut-oif-s interposed, to receive the falling stalks, andprevent them from falling upon the platform until the proper moment.After the gevel is discharged, the platform falls again, the eut-oit` iswithdrawn, and the stalks fall upon the platform as before.

In the accompanying drawings, which show one practical way of carryingout our invention, a'vstout main frame, A, is shown as mounted on twosupporti11g-wheels, B B, which may either turn loosely on a'xed axle, orbeixed onv :in axle turning iu bearings in theframe, as preferred bytheconstructor. Aitongue, C, projects from the front of this frame, in aproper position to regulate the side-draught. The platform E is securedupon a supplementaryframe, l), the forward end of which is pivoted tothefront of the main frame by hinges which allow the frame to playvertically, in order to raise or lower the cutting-apparatus andplatform. i

An arm,F, pivoted, ntf, to the supplement-ary frame, (so as to allow itto play vertically parallel with that frame,) and carries a roller, G,on its lower end. A bracket, F', projects upward from this arm.Setscrcn's a and 4Z', upon the main and supplementary frames, entervertical slots in this bracket, by which means we can leave thesupplementary or platform-frame free to vibrate vertically on its pivotsd, or vary the angle of the main frame, or the height'of thesupplementary frame, at will.

AThe platform E is solid, and projects laterally beyond the main frameon'one sde, in order to support the p cutting-apparatus, which, in thisinstance, is shown as consisting of a fixed seythe, A bracel, attachedto the inner front corner of the main frame, and to tlie'platform, nearthe heel of the cutter, serves to strengthen theplatform. i

A divider andgrain-guard or fence, J, are mounted on the grain-end ofthe platform.

A vertical reel-post, K, is mounted, in suitable bearings, on an arm,7c, projectingfrom the main frame, and rotated by a band,- b, encirclinga pulley, Vb, on the inner driving-whcel, and a similar pulley, c, onthe rcel shaft. Cross-arn1s K' are mounted on the reel-shaft, andrevolve with it.

A curved guide-rod, L, is secured to the divider-end of the platform,and curved, as shown in the drawings that is to say, it is bentforwards, and then backwards over the divider, and then turnedhorizontally over and parallel `to the rear edge of the platform. Thisrod, it will be perceived, is supported at the grain-end only, in orderto leave an unobstructed space for the discharge of the stalks, ashereinafter explained.

A series of parallel slats or bars, in, are arranged, parallel to eachother, upon a rock-shaft, M, turning in bearings in the hack of theplatform E. rlhe rear ends m of these bars are turned up,'to form afence or guard,

toprevent the premature dropping of the stalks, while their front endsare connected by a'red, N, turning in eyes in the bars.' The grain-endof this rod is bent up at a right angle, and slides cndwise througha-hole in an armO, on the main frame. Thus, when the bars are thrown upperpendicularly, the rod extends across the platform about the level ofthe guide1od, a-nd intercepts the falling stalks. When the bars lie daton the platform, the rod is vertical, and, consequently, out of the way,as it lies close to its arm O.

The grated platform is tilted by means ofia hand-lever, It, pivoted onthe mainframe, and connected with the platform by a link-rod, l?. Thislever is worked by the driver from his seat S. The platform might, hoW-ever, betilted by a footlever as well. i l

In operation, as the standing stalksl are'severed` bythecuttinghpparatus, they are swept back by thereel and guide-rod, andcaused to fall upon the grated platform.',"Wl1en.a gevel of sufficientsize has accumulated, the driver seizes the lever R, and tilts thegrating into thefposition shown in red in fig. 2,- when the stalks aredischarged upon the ground. As the guide-rod L has no support `at thestubble-end, the long stalks may be dis charged without obstruction. Asthe grating tilts, the cut-oilv1 N isn thrown across the space betweenthe guide rod L and 'the reel, through which thefalling stalks mustpass, andthus intercepts the stalks which fall during the dischargeofthe grain. As the grating is lowered, thecut-ordrops, and allows the cutstalks resting against it to fall upon the gratinfr. t

The roller G holds up the platform, and prevents the link-rod P from,striking the ground. The shoes T also keep the platform from contactwith the ground.'

What we claim as our invention, and desire to securel by Letters Patent,is-

l. A cult-olf, N, having an endivisc movement parallel to the-path ofthe machine, substantially as set forth'.

2. The combination, substantially as set forth, with. a Vtiltngplatform,of a cut-off, vibrating endwise at a right angle to theaxis of theplatform," and parallel to thepath of the machine'. Y

3. The combination, substantially as set forth, with a tilting-platformand a cut-olf, of a guide or deilcctor,

`supported at the grain-end only.

4. The combination` and arrangement, `as set forth, with the reel,revolving on a vertical axis, of the tiltingplatform. y y l 5. Thecombination, substantially as set forth, of a laterally-projectingcutting-apparatus, a rcel, revolving on a vertical axis, -a guide, acut-olf, land a 'tilting-platform.

6. VThe combination, substantially as set forth, of the main frame andsupplementary fr ame with tbe rollerarm F and bracket F', for thepurposes set forth.

' 4In testimony whereof, we have hereunto subscribed our names.
